Dear Dr. Zhang, thanks again for your kind support. We will consider involving clustering or integrating with learning-based detection before the fine refinement based on your pipeline. The unexpected dynamic objects are quite challenging for large-scale mapping, especially in dense urban such as Hong Kong. Hopefully, we could have a chance to collaborate on dynamic object removal in the future.

Thanks for sharing, I checked, it looks like you forgot to save the pose in the VIEWPOINT
field: https://kth-rpl.github.io/DynamicMap_Benchmark/data/#a-header-example
And here is an example way to save (C++/python):
// set the viewpoint -> CHECK PCD VIEWPOINT FIELD
pcl_cloud->sensor_origin_ = Eigen::Vector4f(pose[0], pose[1], pose[2], 0.0);
pcl_cloud->sensor_orientation_ = Eigen::Quaternionf(pose[6], pose[3], pose[4], pose[5]); // w, x, y, z
// save the pcd
std::ostringstream tmp_filename;
tmp_filename << save_pcd_folder << "/pcd/" << std::setfill('0') <<
std::setw(6) << count << ".pcd"; std::string pcd_file =
tmp_filename.str(); pcl::io::savePCDFileBinary(pcd_file, *pcl_cloud);
In python way:

Thanks for your reply! I will re-implement the Pcd write part and evaluate again.

Dear Dr. Zhang,
Thanks for your reply. The results are impressive after I regenerate the pcd and put it into testing again using Dufomap. However, some areas especially on the opposite road are not good. Is it possible for you to provide some hints on any parameter I could further turn (default config of Dufomap is used)? The update data is provided for your reference. Thank you very much for your time!
The update PCD viewpoint using the SLAM pose,
The car near the sensor is removed
For the cars on the opposite road of the vehicle sensor platform has remained

I checked again and believe this is at the end of the frame, and since the DUFOMap strategy is to build the void(free) map, but the space you show and I pointed out, we don't have enough time/dense info to say that.
And this is one limitation we already mentioned in the paper Sec V-E:

No worry. Let me know if you have any further questions.
